Nano technology – a solution to key issues

Nano Technology is mainly referred to the branch of science and engineering that manipulates matter on near atomic scale i.e. 1 to 100 nanometres for generating new materials, devices and systems.

Nano technology devoted to scientific advancement in diverse sectors like energy, materials, and manufacturing, medicine and consumer products. Modern nano technology actually began in 1981 when engineers and scientists use the scanning tunnelling microscope to view and manipulate individual atoms. However, the concept of nanotechnology was founded by the American scientist Richard Feynman in 1959.

Nano technology used to save the world as the nano technological products, procedures and applications contribute to environment protection by lessening greenhouse gases and saving energy and raw materials. This technology is used in humans and in everyday life to acquire positive impact. Additionally, this technology is significant for giving a novel and enhanced tactic to diagnosis and treatment of cancer.

In the US, over 18 billion dollars were invested during 2001 and 2013 through the National Nano Technology Initiative for turning the sector into the driver of economic development and competitiveness.
